Soil remediation
Agricolture uses
one of the largest amounts of water from natural sources
(rainwater) or alternative sources (water reuse and wastewater
drainage).
About 70% of worldwide water utilization is represented by soil
irrigation. Recycling water is a delicate operation, because it may
have adverse effects on public health and environment. Depend on
this the yield of the land and the consequent quality of the
products.
The remediation of contaminated sites is a very complex problem.
Traditional treatments for soil remediation are biological, thermal
or physical-chemical, but the chemical treatment of soil
remediation of dioxin contamination by ozone may be the most
effective technical, economical and environmentally friendly. Soil
remediation involves the removal of MTBE (methyl tertiary-butyl
ether), hydrocarbons, diesel, pesticides, VOCs (Volatile Organic
Carbon), benzene, toluene, ethylbenzene, xylene, trichlorethylene,
Aromatics and pesticides that can be harmful both for the man who
plants and animals.
In addition, ozone:
- is produced locally so it is not necessary the transport of
hazardous chemicals;
- does not
cause any damage to land and act quickly;
- is a
powerful oxidant that leaves no toxic residues;
- can be
administered in the form of ozonated water in the case of polluting
surface or in the form of gas through subsurface irrigation
systems;
Ozone is directely used on seed to eliminate mold and parassite, or to treat irrigation water to disinfect (mold, viruses, bacteria such as listeria and salmonella or decontaminate irrigations canals (hydrogen sulphide, ammonia and other substances). This is the cheapest and fastest way to disinfect and recycle the rinse water.
